Baleage Tips

May 2015

Many industry experts suggest a minimum of six wraps/bale when making baleage. Vermeer agrees with this recommendation. Various field and crop conditions impact the number of wraps/bale decision; please consult a local expert in your area as you consider this decision.

Percentage of Moisture at Harvest

< 35% Moisture – Less fermentation. Requires an extra layer or two of plastic wrap. And needs to be fed as quickly as possible to reduce aerobic stability issues.

35-45% Moisture – Some fermentation, more layers of wrap needed.

45-55% Moisture – Generally recommended for best results.

55-65% Moisture – Great fermentation, but oftentimes it leaves a wet rank layer (1-2″ deep), which forms on the outside of the bale.

Recommendations on Type/Timing/Dos & Don’ts of Wrapping

First, netwrap the bale. It forms a smoother bale surface all around, containing stems and reducing the possibility of poking holes into the film. (Rodenticide-treated sisal twine has the potential to degrade film.)

Plastic wrap film recommendation – Blown, low-density polyethylene about 1-mil thick, with 70-80% stretch. If you’re really aggressive on stretching, you may need to put another layer or two of wrap on to account for the reduced thickness of the material.

Wrap as soon as possible after baling to prevent aerobic deterioration.

Wrap close to the storage site to minimize handling.

Store away from woods, where rodents and other “critters” are found.

Avoid areas with sharp stubble and poorly drained soil.

Periodically check for stems poking through the film, or rodent damage, and repair immediately.

Don’t wrap during a rainstorm. Wet film loses its tackiness.

Don’t handle bales 12 hour or more after wrapping. Squeezing them can break film layers and potentially expose bales to oxygen, which can restart the aerobic phase.
